The Arduino's board design evolves because of an active community of users who support both the history and future of the product. The Arduino microcontroller advances in its hardware design, software examples and popularity because users document and share code and designs. Open source platforms such as the Arduino microcontroller builds upon the creativity of an entire group of people rather than the small team from which it originated.[1] Arduino is licensed with a share-alike creative commons license. With this license, users of the Arduino are able and encouraged to share designs, reuse, and remix these designs to adapt the Arduino for their work.[2] Several community members responsible for the Arduino's evolution are the artists and designers highlighted in this thesis. However, artists and designers are not working in a vacuum to evolve the Arduino microcontroller. The Arduino microcontroller has rapidly infiltrated different user groups simultaneously so that many areas of study are overlapping. These groups that have had an impact on the Arduino include but are not limited to engineers, hardware hackers, interaction designers, artists, educators, and robotics enthusiasts, exemplified in Section 4.2. Microcontrollers, traditionally used by engineers, are now in the hands of artists and designers working with the Arduino, and vice versa. Engineers are also creating artwork and design pieces. The various groups are blending and using each other's code, materials, and techniques. The lineage behind the Arduino is shown in Figure 3-7. The timeline in Figure 3-7 touches upon influential people behind the designs that guided the Arduino development: Programma[3], Wiring[4], Processing[5] and InstantSOUP.[6]
